Accessibility compliance
WCAG 2.1 AA compliant
MATCHA was designed for accessibility from the beginning. It is screen-reader-friendly and easy to navigate with a keyboard.

Whether your students are writing essays in class, in supervised writing labs, or at home, MATCHA secures writing by making the entire work process transparent to instructors, from reading to editing. It also blocks auto-typers and other forms of automation, securing writing at the source so you don't have to use AI detection after the fact.
In‑class activities
Computers in the classroom pose a challenge to academic integrity. MATCHA secures computer-based writing activities against AI misuse by blocking copy-paste, app-switching, and automation—without requiring special privileges or invading students' privacy.
How it works: Using MATCHA for in-class activities
1
The instructor uses the MATCHA Dashboard to create an in-class activity, enabling Copy-Paste Block and Single-App Mode to prevent students from using AI tools outside of MATCHA.
How MATCHA in the classroom compares to traditional proctoring or exam-taking software
- Integrity without invading privacy: MATCHA does not require administrator privileges, screen recording privileges, camera access, or microphone access. It only needs access to its own files.
- Unbeatable copy-paste protection: Despite its non-invasive design, MATCHA offers strong protections against unauthorized AI response injection (for example, using a virtual machine) because its protections are partly server-side. MATCHA's patent-pending Remote Typing Certification technology cannot be circumvented by virtual machines and NotchGPT (MATCHA also detects and blocks these techniques on the participant's computer).
- A full-featured word processor: MATCHA is a full-featured word processor designed for long writing assignments, not only quizzes or short answers. It supports footnotes, tables, references, and equations, among other features.
- Easy integration: MATCHA produces certified .docx files , which integrate with typical writing assignment workflows.
Unsupervised work at home
At home, we cannot stop students from consulting AI on a secondary device, but we can still strongly de-incentivize AI misuse by making it no easier than doing the work for real. MATCHA achieves this with its Complete Work History and Follow-Up Quiz features. These are not AI detection tools. Complete Work History is a tool for students to share their entire work process (including reading and note-taking). Follow-up quizzes are an opportunity for students to further reflect on their work. These are pedagogical tools that happen to make AI plagiarism prohibitively difficult.
How it works: Using MATCHA for unsupervised activities

Instructors create unsupervised activities with the Complete Work History and Follow-up Quiz features. They distribute access codes to students. They prepare follow-up quizzes using generic (all students) questions as well as AI prompts for student-specific questions.
Key features for unsupervised essay assignments
How MATCHA compares with other edit-tracking software when used at home
- Complete Work History: Other edit-tracking software does not record all browsing and reading, which is key to an AI-proof pedagogy.
- Follow-Up Quizzes: Other edit-tracking software does not generate authorship quizzes or provide a secure environment to take these quizzes.
- Automation Blocking: Other edit-tracking editors run in the browser, which means they can easily be circumvented using browser plugins, auto-typers, and AI agents that can control the browser (now available from major AI vendors such as Claude and OpenAI). Only a standalone app with OS-native functionality can defend against these widespread, off-the-shelf cheating methods.
- More powerful editing features: MATCHA comes with unique and powerful writing tools that facilitate proper academic writing, such as Direct Citing, Auto Citing, and Pedagogical AI.
Can MATCHA really stop AI transcription at home?
It can strongly deter it, but only when the work histories MATCHA generates are used as part of a process-centric pedagogy rather than merely as an academic-offense detection tool.
The best way to use MATCHA to prevent AI cheating at home is to reward students for their effort and the quality of their work, just as we reward students for showing their work on math problems in grade school. The work history that MATCHA generates should be used to reward students for following a good process—for example, reading the right works, taking clear and purposeful notes, and revising their text over time. Used this way, the work history both promotes deeper learning and strongly deters AI cheating.
Likewise, follow-up quizzes should be conceived of first and foremost as pedagogical tools. They are opportunities to help students deepen their reflection on their essays by answering tailored follow-up questions. Students should be rewarded with points for this work as well, both recognizing thoughtful work and further deterring AI cheating.
A student who is determined to avoid writing an original essay will always be able to do so when working from home. But a pedagogical approach that places process and follow-up reflection at the center of assessment makes it difficult to earn a good grade without doing the work. That is key to restoring fairness in at-home assignments.
Supervised writing lab assignments
Supervised writing labs are classrooms or other spaces where students can work on their long assignments in their own time. As with classroom activities, MATCHA prevents AI misuse on the student's computer while the on-site proctor prevents other devices from being used. Proctors use MATCHA's Check-In feature to ensure that students don't continue working on their assignments outside the lab.
How MATCHA compares
MATCHA enables supervised writing labs by allowing writing supervisors to control when a document can be accessed and/or edited. Unlike traditional exam-taking software, MATCHA allows an activity to be continued across multiple sessions. No other product has equivalent functionality.
Case study
Case Study: Supervised Writing Labs at Western University
MATCHA began as a software solution for supervised writing labs at Western University. After experimenting with edit-tracking software, we found that far too many students, over 30%, were transcribing or auto-typing AI-generated essays. In most cases, however, the evidence was still not strong enough to support a formal academic offense. That limitation made edit-tracking alone an inadequate response.
Are your students on social media instead of taking notes in class?
Make note-taking a MATCHA Single-App Mode activity
At the end of class, the MATCHA attendance sheet will tell you who was in the activity for what time period, and you will know they were focused on taking notes. Reward submitting notes with participation points and you will significantly increase in-class engagement.
Accessibility and privacy
Complete privacy and security
Local-first by design
MATCHA is an installed desktop app, so students' personal information never has to be processed by third-party servers. It offers strict privacy operating modes respecting the highest levels of privacy, from No Personally Identifiable Information shared to Zero Trust.
